HO ACF4600 Covered Hopper BN #455990 (ATHG-1537)

HO Scale ACF 4600 Center-Flow 3-Bay Covered Hopper, BN 455990, is a highly detailed model that recreates the mid-1960s bulk-carrier used for grain and similar loads. The Center Flow design relies on a rounded body to provide structural strength and gravity unloading, and the model captures that look with an injection-molded body, accurately painted and printed finishes, and a weighted chassis for smooth operation on HO track.

The detailing reflects the era: three body styles (early with a high side ladder and brake wheel; mid with a low brake wheel and short ladders at both ends; late with double side stiffeners added after 1971), round or trough hatches, and a photo-etched roofwalk with separately applied wire grab irons, stirrup steps, and brake wheel. It rides on screw-mounted trucks with Genesis 100-ton assemblies, 36-inch machined metal wheels, and animated spinning roller bearing caps, while body-mounted McHenry operating scale knuckle couplers supply authentic coupling. An 18-inch minimum radius makes it compatible with a wide range of HO layouts, and the finish is primed for grime with faded, dull base colors that form a natural starting point for weathering. Prototype context notes that the 3-bay Center Flow hopper debuted in the mid-1960s to replace older boxcars in grain service and remains a familiar sight in modern grain trains.
